FS: Wilson K90 4 1/4 in 7.5/10 condition

I have a Wilson KFactor Six-One Tour 90 a.k.a. K90 in 4 1/4 grip, in 7.5/10 condition. The racket, which is based on the Wilson Pro Staff 6.0 that Pete Sampras used his entire career, has a great combination of power, spin, and control. At 12.6 oz strung, it swings very nice during actual rallies. Like most of Wilson's midsize rackets, this one has a stock leather grip that allows you to feel the bevels and gives you better feel, even with the use of overgrips. The racket is strung with Babolat Hurricane mains and Gosen OG Sheep crosses at 57 lbs. Link to photos below.
